You really have to look for Ac virga clouds which are often seen also with iridescence which you can see at images of mine.<br>Also You should cover the sun with something sharp like chimney or street lamp or something like that ;).<br><br>Michael: Is your time-lapse of that ellips somewhere on the internet ??? Because it sounds very tasty... ellips time-lapse :).Matěj Greknoreply@blogger.comtag:blogger.com,1999:blog-1046232325583098770.post-58442392873395437282009-01-22T12:11:52.000-08:002009-01-22T12:11:52.000-08:00Its not online yet but if I can help to turn the s...Its not online yet but if I can help to turn the still frames into a movie I will do that. I was amazed with the way the halo would shrink as the crystal cloud layer would move. It did this three times and it always started when a piece of AC cloud would preciptate as it would move in front of the sun and then halo fragements would coaless into a large elliptical halo with two or more ellipses then it would shrink.<br><br>When the vid is made I will go to youtube and upload it and then post a link.Michaelnoreply@blogger.com
